☘️❤️🔵WHERE DID THE YELLOW COME FROM? 🔵❤️☘️ . When red, green, and blue (RGB) light combine at full intensity, they create white light. This happens because our eyes have three types of cone cells that detect these colors. When all three cones are stimulated equally, our brain perceives white! This is how screens and projectors create full-color images using just RGB light. . Once the colors are combined, when the light diffracts around an object or through an opening it spreads out. This separation creates a spectrum, and overlapping wavelengths can mix to form secondary colors like cyan, magenta, and YELLOW! . .
